- TWINE-CAN FOR. SELF-BINDING HARVESTEBS.

To all whom-it may concern:

Be it known that I, IRVING E. BRowN, a citizen .of the United States,residing at Sebewa, in the county of Tonia. and State of Michigan,haveinvented a new and useful Twine-Can for Self-Binding Harvesters, ofwhich the following is a specification.

My'invention relates to improvements in twine-cans for selfbindingharvesters, and the objects of, my improvement are: First.

twine. Second. To make possible the tying of the, ends of the ballsafter their insertion. Third. When the. upper ball is exhausted, tofacilitate raising the lower ball to the position formerly occupied bythe upper ball, so that a new .ball may be inj serted; beneath it andthe tying process re peated. Fourth. To prevent the entanglement andconsequent breakage of twine inside the can. I attain these objects bythe mechanism illustrated in the accompanying --.drawi'ng, in which allfigures are views in perspective.

Figure-1 shows the twine-can partly opened; Fig. 2, partly opened andwith theouter groove-bands removed; Fig, 3, closed and fastened; andFig. 4, from the rear, with its opened door passing between the body ofthecan and the bracket.

Similar .letters refer' to similar parts throughout the several views.

Before explaining the merits of my in vention it is necessary to referto the imperfections of the twine-cans now in nse on all self-bindingharvesters. In this type of can the twine-balls are inserted from thetop, which is closed by a hinged cover. --'hen the upper ball isexhausted, the remaining ball must be extracted from the bottom of thecan and held in the hands or laid in a precarious position on theharroster while a new ball is placed in the bottom of the can and itsend tied to the 0nd of the ball before mentioned. This hall must then beplaced in the can on top of the new ball-au operation which can not beperformed without leaving unwound fifteen or eighteen inches of twineadjacent the knot which connects the balls. Consequently when the upperball is nearly exhausted, the torsion of the unwound twine near theknot, combined with the jar and vibration of the machine, frequentlycauses entanglement and breakage of twine inside 1 119 238 Specificationof Letters Patent.

the can. These annoyances, are eliminated partments by the slotted shelfC, to which is riveted one end of the twine-latch D, in

a manner which, When the door is open, pernits the twine-latch to bemoved laterally to the position shown in Fig. .2; The slot S, which inFig. 1 is almost concealed bv.

the twine-latch D, extends from the edge of the shelf to its center, andis Ofsufiicient width. to permit the )assage of the knots which connectthe ball s of twine.

Fig. 1 shows the upper compartment empty, as when a new ball is to beinserted.

By sliding the twine-latch D to the position shown in Fig. :2,the'tWine-thread T may be withdrawn from the slot S in the shelf and theball instantly transferred from the lower to theupper compartment. A newhall may then be placed in the lower com-,

partment, as shown in Fig. 2', and its end tied to the end of the ballabove it without unwinding one superfluous inch of twine. Thetwine-thread above the knot is then placed in the slot S, thetwine-latch D is closed, holding the thread securely in the slot, andthe door A is closed, which holds the twine-latch D firmly in, position.To prevent the twine-latch from slipping farther inward its outer edgeis curved over the edge of the shelf C.

ln'the door A are peepholes H H, which enable the operator, withoutopening the door, to tell when either compartm-"nt is empty;

A knob E is attached to the door for convenience in opening and.closing. When closed. the right-hand edge of theduor meets at top andbottom the shoulders V V of the narrow groove-bands F F (Fig. 2); and aspring catch G, projecting through the side of the can directly behindthe door A, engages the edge of the door and pro rents it from openinguntil released by the pressure of a finfrcr. Dotted lines indicate. theposition of this spring catch inside the can.

Probably the cheapest method of (onstrncting, the grooves B B is shownin Fig. 2. Two bands I I, of the s-aznc -E'lfi llll and thickness as thebands J J, encircle the can, one at the top and one at the bottom; Thesebands are of about the thickness of the door A. Encircling the bands I Iare the bands F F, slightly thicker and much narrower except at theshoulders V V and for a short distance from them. Encircling the bands FF are the bands J J. Bands I and J thus form the sides of each groove B,while band 1 forms the top and bottom of the upper and lower grooves andalso gages'thethick ness"thereof. Band s' 'l and J may be constructed asa single wide band doubled lengthwise over band F. Rivets passingthrough all three bands fasten them tightly to the can. A light casting,embodying the essential features of the bands, may form the grooves moresatisfactorily at slightly greater cost. 7

The bracket K is riveted or bolted to the twine-can at pointsL; and whenopened, the door A passes freely between the can and the verticalstem-of thebracket. In Fig. 4 the bracket is shown connecting the canwith the frame of an Osborne grain harvester at M. The attaching featureof the bracket "may be varied to meet the peculiarities of every make ofgrain and corn harvester.

I claim: 1

l. A twine-can for self binding harvesters, comprising'a case having anopening at one side, and a slotted shelf positioned horizontally in saidcase between the top and bottom thereof, the slot in said shelfextending from a side thereof adjacent the opening in the case,substantially as described.

2. A'tWine-can for self binding harvesters comprising a case having anopening at one side, a slotted shelf positioned horizontally in saidcase between the top and bot tom thereof, the slot in said shelfextending from a side thereof adjacent the opening in the case tosubstantially the center of the shelf and means for closing said slot atits outer portion, substantially as described.

3. A twine-can for self binding harvesters comprising a case having anopening at one side, a slotted shelf positioned horizontally in saidcase between the top and bottom thereof, the slot in said shelfextending from a side thereof adjacent the opening in the-case tosubstantially the center of the shelf, a door for closing the opening inthe case, and means for closingthe outer portion of the slot, said meansbeing held in operative position bythe door 'when it is in closedposition.v

4. A twine-can for self-binding harvest- I ers, consisting of.acylindrical case closed at top and bottom fill 1d provided with a sideopening, a slotted shelf which divides the case into two compartmentsand to which is affixed a twine-latch, and a door which moves laterallyin grooves to close the opening, all substantially as set forth.
